Right, I forgot. Unfortunately, no luck with gksudo anyway.
As for pkexec, I want to try again:* On another machine with gnome shell, the command "pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY" is the only one that worked. * it's odd as no files related to nautilus in the /usr/share/policykit1/actions, whereas installing nautilus-admin installed it on the non-working machine.
